Table 2 to Table 6 list the jumper settings on the CYW955913EVK-01.

Table 7 lists the buttons and switches on the CYW955913EVK-01.

J1, J2, J3, J4, and J5 are Arduino shield-compatible headers.

J9 is the JTAG/COEX header, which brings out the WL GPIOs of the CYW55913 device (not mounted by default; see the Kit reworks chapter for use).

J22 is a UART programming header using an external device that brings out the HCI UART pins of the CYW55913 device (not mounted by default; see the Kit reworks chapter for use).

A CY8C5868LTI-LP039 PSOC™ 5LP chip is used for onboard programming and USB-serial functionality. It connects the kit to the PC over a USB interface and to the CYW55913 device through the HCI, peripheral UARTs, and I2C pins. Optional SPI and JTAG connectivity are also supported by this chip.

The CYW955913EVK-01 kit can be powered with the following power inputs:

• USB Type-C connector (J6)
• 5 V - 12 V, 1 A DC jack (J7)
• VIN pin of the J1 header (J1.1)

The input supply is provided to the buck regulator to generate 3.3 V for the VBAT supply of the device, and from the same 3.3 V; for the peripherals, 1.8 V is generated using an LDO. For more details about the power regulators, see the Hardware section.

There are three ground test points for easy connection of probes. Table 16 lists voltage at various domains that can be measured from their respective test points on the baseboard.

CYW955913EVK-01 has a VBAT (3.3 V) power domain to power the CYW55913 device. Current consumption of the M.2 carrier module with the CYW55913 device can be found out from the current consumed by the VBAT domain.

GPIOs on the CYW55913 device can be multiplexed to various peripherals. For more information on the peripherals that can be routed to the various GPIOs; see the device datasheet.

The baseboard design of the CYW955913EVK-01 board is designed to be modular so that different carrier modules can be used with the same baseboard. In this kit, the CYW955913SCM2WLIPA M.2 carrier radio module, which employs the CYW55913 device, is connected to the baseboard through the M.2 interface.

The carrier module interface is a generic interface used across many devices. See device I/O mapping for a detailed interface description. SDIO, UART signals, and GPIOs are moved out from module pins to interface with the baseboard.

CYW9CPM2BASE1 is the baseboard on which the CYW55913 M.2 carrier module (CYW955913SCM2WLIPA) is mounted. The baseboard is interfaced with the M.2 carrier module through the M.2 E-Key connector, and it provides different peripherals and extended connectors to demonstrate the capabilities of the CYW55913 device.

To enable the JTAG/COEX access from the kit, you need to mount the J9 connector and resistors R211, R212, R213, and R214 to connect the CYW55913 device GPIOs to J9 and need to isolate the connection to the KP3 by removing resistors R210, R216, R217, and R218.

To enable the external UART programming, you need to mount the J22 connector and level translator (U24), which is not mounted by default. The path to the connector from CYW55913 can be enabled by mounting R219, R220, R221, and R222 resistors and removing the connections R137, R139, R141, and R142 resistors.

CYW55913 device major interfaces can be switched to the external host interface or Arduino header by mounting the series resistor in the path between the device and the external connector or to the Arduino header in the multiplex options.
